Abstract: The effects of bagging on fruit quality of ‘Xinshiji’ guava(Psidium guajava)were studied. The results showed that bagging could accelerated growth of fruits and increased fruit size and weight markedly. Transparent bag and red bag had no effects on TSS (total soluble solids)and bagging with black bag decreased the TSS in fruit. Treated with bagging, the plant diseases and insect pests decreased, the fruit coat became smooth and fruit color were improved.

摘要： 以新世纪番石榴品种为试材,研究套袋对番石榴果实品质的影响。结果表明,套袋可加速番石榴果实发育,明显增加果实大小和重量;透明和红色套袋对果实可溶性固形物含量影响不大,黑色套袋降低了果实可溶性固形物含量;套袋使果皮光滑,病虫害显著减少,并改善了果实着色。
